I've been wondering, if I wanted to make an Expert Belt set to take advantage of his Strong Jaw coverage options, what would the ideal set be? Obviously, you're angling for super effective hits to get the Belt boost, so you're not necessarily aiming for the best neutral coverage, which is the usual benchmark. Might Crunch be a superior coverage option on an Expert Belt set because it nails Ghosts and Psychics?
Something like this:
Tyrantrum @ Expert Belt
Ability: Strong Jaw
Nature: Adamant or Jolly?
EV Spread: 4 HP / 252 ATK / 252 SPE
- Stone Edge
- Fire Fang
This seems to be the mandatory set-up, but what about the last two moves + nature? Crunch hits Ghosts and Psychics, Thunder Fang hits Water types only (since Stone Edge hits Flying types harder) Ice Fang hits Dragons, Grass and Ground types (again, Flying is best handled by Stone Edge), Earthquake hits Rock, Electric and Heatran (Fire Fang handles most Steels and Stone Edge most Fires). Dragon Claw is basically outclassed by Ice Fang, which hits most relevant dragons harder and we're looking for maxing out SE hits here, not neutral coverage, so we've little use for a Dragon-type move. Finally, there's Dragon Dance as an option, which reduces your coverage but increases chances for a sweep and allows you to outspeed and OHKO certain threats. However, this being said, there are some switches where hitting the switch-in with a good prediction is far better than simply taking advantage of the free switch to DDance, like Scizor and Lucario who have SE priority to ruin Tyrantrum's day with.
From that, it looks to me like Ice Fang is the best choice for slot 3, and then you take either Crunch or Dragon Dance. Thoughts?
